Solve for x: -3|x + 7| = -12

Answer 1

divide -3 on both sides then tell me wat u get

Answer 2

-11?

Answer 3

-3|x + 7| = -12
\[|x + 7| = \frac{-12}{-3} \rightarrow |x + 7| = 4\]
\[ x + 7 = \pm 4\]
i.e. \[ x + 7 = 4\] or x + 7 = - 4
i.e. x= 4-7 or x= -4-7
i.e. x= -3 or x= -11 is the required answer.

Answer 4

no i just said to divide by -3 on both sides not to solve the whole problem

Answer 5

i wanted to see if u knew how to work the problem just not to give u the answer

Answer 6

we can simply do -3|x + 7| = -12
|-3x-21|=-12
3x+21=-12 asafter retriving any value from modulas the sign is changes to positive
x=-12-21/3
x=-11
